New ferrite material improves split-core current transformers for power measurement

LEM Split Core Transformer

A few years ago, engineers designing split-core current transformers for the 50/60 Hz application domain were dreaming about “magic” materials for magnetic cores, which would provide the best performance at the best price. Unfortunately the available technologies offered either a good performance for a high price or much poorer performance for a low price. Although […]

What You Need to Know About Current Sensors

LEM Current Sensors

When it comes to current sensors, you have two main options: open look or closed loop. Open loop current sensors can measure either AC or DC current and offer you electrical isolation between the circuit you are trying to measure and the output of the sensor in order to provide you with a more accurate […]

The Benefits of Using Split Core Transformers

LEM Split Core Transformer

  If you’re looking at current transformers, you really have two choices: split core transformer and solid core transformer. A contactless, split core transformer’s main claim to fame is its ability to be snapped over pre-existing wires, making them ideal for retrofitting projects and more. There is no need to screw or weld any type […]
